Abstract
A temperature compensation circuit includes a voltage generator, a comparator and an emulation cell array. The voltage generator provides a predetermined voltage and a reference voltage. The comparator has a first terminal for receiving the predetermined voltage, and a second terminal for receiving the reference voltage. The emulation cell array is coupled to the first terminal of the comparator. When a voltage of the first terminal of the comparator is discharged, via the emulation cell array, to be lower than the reference voltage, the comparator outputs a read timing control signal to control a sense amplifier to perform a sensing operation.
